They had a decent attack when Westfield was playing along with Chambers. To be fair, home games at either club wont be that bad for you to get to as the a12 is direct to both clubs, BUT, when the Olympics are on you will struggle as they both are so close to the olympic park.
So, you are 30, played some games for Essex when you were younger,,,,,,, sorry, trying to do some detective work lol.
Good luck with what ever you choose. If you are a decent player and have played pro or somewhere near to that effect, then there are alot of Essex based clubs still looking for a 'pro'
